Bi_6Te_2Mo_2O_(21)—A New Synthetic Crystal and Its Physical Properties

Bi_6 Te_2 Mo_ O_(21)是仿天然赤路矿成分,在 Bi_2 O_3-TeO_3-MoO_3三元系相图中进行人工合成的新晶体。晶体尺寸为700×300×300μm^3,经物理性质和晶体结构测定初步表明,该晶体在反光、声光特性方面有应用前景。

Single crystals of the recently discovered natural mineral,Chilumite Bi_6Te_2Mo_2O_(21),of dimensions up to 700×300×300μm,have beensuccessfully synthesized from the ternary system Bi_2O_3-TeO_3-MoO_3,and theircrystal structure and physical properties have been determined.The crystalbelongs to the orthorhomibic system and D_2~6-C_(222) space group with latticeparameters a=5.602(?),b=5.553(?),and c=22.816(?).The data of other physicalpropeties such as refractive indexes,reflectivity and IR spectrum of thecrystal are also given,and its the potential applications are discussed.
